Solder paste is not tinned, the more active the better?
Dec 15, 2022
12-15
2022
Recently, many people are asking, if the solder paste is not tinned, everyone will find out whether the activity of the solder paste is too low, but some people will say that the more active the better, is it easy to tin? What I can tell you is that it is not to eat, why? The following solder paste manufacturers will explain to you:
Everyone knows that there are many additives in solder paste, one of which is called activator.
Solder wire welding method

Many people now know that solder wire is composed of tin alloy and additives. Different types of solder wire will produce different fluxes. The oil on the surface of the welding material will increase the welding area.
Hotspots and Difficulties Analysis of Solder Ball Technology Development
Dec 14, 2022

2022
In order to prevent problems such as bridging of solder balls in the electronic connection process of BGA or FlipChip packaging with finer pitches, and to use the "self-alignment effect" of solder balls in the melting process, the solder balls used in BGA packaging, It has very high dimensional and shape precision requirements. In order to produce solder balls that meet the requirements of solder ball surface quality and dimensional accuracy, various technologies have been tried and some technical solutions have been used in production, but in order to obtain better production technologies, there are still quite a few domestic and foreign Research is invested in solder ball production technology.

2022
The main factors affecting the welding quality of tin wire are welding current and energization time, electrode pressure and shunt, etc.
1. Tin wire welding current and energization time
According to the size of tin wire welding current and the length of energization time, spot welding can be divided into two types: hard specification and soft specification.

The printer should be responsible for the quality of the solder paste on the printed boards, and cannot pull down the boards with tin, less tin, or more tin.
What is the impact of weather and temperature changes on solder paste?
Dec 12, 2022

2022
The main products in the soldering industry are solder paste, tin wire, and tin bar. The main raw material for soldering is tin. When the weather is low, the crystal form of tin will be changed, making tin brittle. At present, we All electronic products used have minimum and maximum operating temperatures, so tin is no exception. What impact does the change of weather and temperature have on soldering tin? I have collected some information for you to organize as follows:
What are the differences between 3.0 silver and 0.3 silver in lead-free solder paste
Dec 12, 2022

2022
As a necessary material for reflow soldering in the solder industry, solder paste can be divided into lead-free solder paste and leaded solder paste according to environmental protection standards. Among them, there are 3.0 silver and 0.3 silver environmentally friendly high-temperature solder paste in lead-free solder paste, both of which are Silver-containing environmentally friendly lead-free solder paste series products have passed ROHS certification and are used in SMT reflow soldering processes. So what is the difference between the two, the double Chilean solder manufacturers summarize as follows:
